YIELECTRIC COATINGS ON VEHICLES CAN ALTER THEIR RADAR IMAGE SIGNIFICANTLY. THIS PROPOSAL IS DIRECTED TO DETERMINING NUMERICALLY THE REFLECTIVITY FOR AN OBJECT COVERED BY A DIELECTRIC LAYER. A CALCULATION WILL BE DONE USING BASIC PHYSICAL PRINCIPLES TO DEFINE THE THEORETICAL BOUNDARY VALUE PROBLEM FOR THE DIELECTRIC LAYER. THE SOLUTION TO THIS PROBLEM WILL BE OBTAINED NUMERICALLY USING MATRIX INVER ...

Wind noise in outdoor measuemetn micropnones can mask an acoustic signal. Windscreens provide some wind noise reduction; however, those typically used for outdoor applications provide noise reductions of approximately 10-15 dB. Planning Systems Incorporated (PSI) proposes to design and test a Multiple Aperture Sensor System (MASS) consisting of a microphone, a processor, and data acquisitio and ...

The project objective are to develop a new software method for the dynamic analysis of aircraft and to prove the potential of unique high angle of attack Leading Edge Vortex Control (LEVC) devices. The software method will be an upgrade of a current computer code. The upgrade will include the effects of hysteresis during dynamic stall. New methods recently published employing state-spac ...

Investigation of failed composite components requires tress analysis to assess their structural integrity. Currently there exist no general-purpose software packages for composite structural analysis that are accessible to failure investigators who are not experts in these types of analysis. The proposed research and development effort will fill this void with a flexible user friendly, PC-based ...

We describe laser communication concepts that result in an untethered Helmet Mounted Display (HMD) virtual reality system. Current systems limit user mobility by requiring wired communication connections between the HMD and the system computer. Our proposed concepts replace the tether with wireless optical communication links. A high-data-rate forward link is provided to carry digital video data ...

PacAstro has shown that significant cost reduction and operational advantages are possible for small orbital and suborbital mission using a simple pressure fed, LOX/Kerosene vehicle configuration. Under private and government funding, we have begun development of the engine which is critical to realize extremely low cost, highly reliable and highly capable space transportation. Beginning with a p ...

VERSAR PROPOSES TO EXAMINE THE EFFECTIVENESS OF COMMERCIALLY AVAILABLE CLAYS SUSPENDED IN LIQUID MEDIA TO REMOVE ORGANOPHOSPHORUS POISON, MUSTARD, PROTEINACEOUS MATERIAL, AND POLYNUCLEOTIDES FROM CONTAMINATED OBJECTS. THIS EFFECTIVENESS WILL BE EVALUATED BY MEASURING AND COMPARING THE COMPONENTS OF THE PARTITIONING/SORPTIVE PROCESS THAT ARE RESPONSIBLE FOR REMOVAL OF THE AGENTS. PHASE I EXPERIMENT ...

EACH YEAR A NUMBER OF PREVIOUSLY VISUALLY-QUALIFIED USAFA CADETS BECOME UNQUALIFIED ON THE VISUAL PORTION OF THE PHYSICAL EXAMINATION AND BECOME INELIGIBLE FOR PILOT TRAINING. THE INCREASED MYOPIA IS A SIGNIFICANT PROBLEM FOR THE AF ACADEMY WHICH IS MANDATED TO GRADUATE A MINIMUM NUMBER OF PILOT-QUALIFIED CADETS. ALTHOUGH THE UNDERLYING, MECHANISM FOR THIS INCREASE IN MYOPIA IS UNKNOWN, A MEASURE ...

THE PROJECT WILL FIRST INVESTIGATE MEANS BY WHICH CONTENT-ADDRESSABLE MEMORY TECHNIQUES COULD BE EMPLOYED IN C3I SPEECH RECOGNITION. IN THE SECOND PHASE, A HARDWARE/SOFTWARE IMPLEMENTATION OF SELECTED TECHNIQUES WILL BE CONSTRUCTED. THE SPECTRAL AND TEMPORAL CHARACTE RISTICS OF SPEECH ARE REGISTERED AS ELEMENTS IN "FEATURE VECTOR SPACES." THE RESEARCH IN PHASE I WILL FOCUS ON UNDERSTANDING HOW THE ...
